Indian scientists have developed a super critical carbon di oxide Brayton test loop facility that would help generate clean energy from future power plants including solar thermal.The technology is perhaps the first test loop coupled with solar heat source in the world. The Brayton test loop facility was inaugurated by Science & Technology Minister Dr Harsh Vardhan at the IISc campus in Bengaluru. It is touted to be India’s first supercritical-CO2 Brayton cycle test bed, and perhaps the first ever coupled with a solar heat source, was inaugurated at the Indian Institute of Science (IISc), Bengaluru.
Super critical carbon dioxide (S-CO2) Brayton Test Loop facility:
It is first test loop technology coupled with solar heat source in world that will generate clean energy from power plants, including solar thermal. This Facility is a next generation technology loop was developed indigenously by Indian Institute of Science, Bangalore. Brayton cycle test loop is designed to generate the necessary data for future development of scaled up S-CO2 power plants, which would require overcoming several technological challenges –developing critical components such as the turbine, compressor and heat exchangers that can work at the desired pressure and temperature ranges and using materials that can withstand these conditions.
- This facilty is designed to generate the necessary data for future development of scaled up S-CO2 power plants, which would require overcoming several technological challenges –developing critical components such as the turbine, compressor and heat exchangers that can work at the desired pressure and temperature ranges and using materials that can withstand these conditions.
- There are many advantages of using this new technology which includes power generation and making the process more efficient. About 50 percent or more─if S-CO2 is operated in a closed loop Brayton cycle which increases efficiency energy conversion.
- This Brayton Test Loop facility facility is part of the Indo-US consortium — Solar Energy Research Institute for India and the United States (SERIIUS). Under the Indo-US Joint Clean Energy Research and Development Centre programme, the Funding for this project was provided by the Indian government’s Department of Science and Technology.
- The term “supercritical” describes the state of carbon dioxide above its critical temperature of 31°C and critical pressure of 73 atmospheres making it twice as dense as steam.Supercritical carbon dioxide (sCO2) is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure.S-CO2 operated in closed loop Brayton cycle increases efficiency of energy conversion by as much as 50% or more.
Indian armed forces successfully conducted first night trial of nuclear-capable surface-to-surface short-range ballistic missile Prithvi-II from a defence test facility off Odisha coast. Mounted on a Mobile Tatra transporter-erector Launcher (MTL), the indigenously developed missile mounted on Mobile Tatra transporter-erector Launcher (MTL) was test fired from launching complex III (LC-III) of Integrated Test Range (ITR).
From Abdul Kalam Island, this was second test of the missile in two weeks and the test came a day after successful trial of 2,000 km range Intermediate Range Ballistic Missile (IRBM) Agni-II .
Prithvi-II is India’s first developed and inducted indigenous surface-to-surface strategic missile.It can be fired anytime and in any terrain in short notice as the test proved the reliability of the weapon and reconfirmed its operational readiness.
Prithvi-II, capable of attacking targets at a range of 350 km, is India’s first developed and inducted indigenous surface-to-surface strategic missile. It was first test-fired on 27 January 1996 and the development stages were completed in 2004. The missile is capable to measure deceive anti-ballistic missiles. It is a single-stage liquid-fueled missile having a maximum warhead mounting capability of 500 kg, but with an extended range of 250 km.
- India today successfully conducted a night trial of its indigenously developed nuclear capable Prithvi-II missile with a strike range of 350 km, from a test range in Odisha. The surface-to-surface missile was test-fired from a mobile launcher from launch complex-3 of the Integrated Test Range at Chandipur , as part of a user trial by the Army.
- The Missile was monitored by the scientists of the Defence Research and Development Organisation (DRDO) as part of training exercise, and was randomly chosen from the production stock and the entire launch activities were carried out by the specially formed Strategic Force Command (SFC) of the Army.
- the nine-meter-tall, single-stage liquid-fueled Prithvi-II is the first missile to have been developed by the DRDO under the Integrated Guided Missile Development Programme (IGMDP) since Inducted into the Armed forces of the country in 2003.
- The missile reached the predefined target in the Bay of Bengal with a very high accuracy of better than 10 meters by an accurate Inertial Navigation System (INS) and controlled by the thrust vector control and Aero-dynamic control systems. The electro-optical systems located along the coast have tracked and monitored all the parameters of the missile throughout the flight path.
